Ship your AI-powered iOS app in days, not months. SwiftAI Boilerplate Pro is a production-ready iOS foundation built by an iOS engineer with 10 years of commercial experience, who has shipped multiple production apps. It includes everything you need to build and launch AI chat applications with authentication, subscriptions, and analytics out of the box.
v2.0.0 is live: Swift 6 and iOS 26 Liquid Glass. Requires Xcode 26.2+. See the changelog and the migration guide.
All setup, integration, and publishing steps are explained here on these docs. For customization and design patterns, see the corresponding files under /docs in your project.

Architecture Overview

Built with modern iOS development best practices:
  • Swift 6 strict concurrency - @MainActor, @Observable, explicit any, Sendable boundaries
  • iOS 26 Liquid Glass - SAIGlass primitive with automatic Material fallback on iOS 17–25
  • MVVM Architecture - Clean separation of concerns
  • Dependency Injection - CompositionRoot pattern
  • Protocol-Oriented - Swappable implementations
  • SwiftData - Modern persistence (iOS 17+)
